🔒 so im trying to code a password tester and a username tester

[obsidian prawn]

I’m trying to code a login system. I already built a password tester and a username tester, and they work. Now I want to add a feature where the user can log in, and if they don’t already have an account, it should allow them to create one.

login = input('please login, if you dont have a account please create a account')

username = input('please make a username ')
password = input('please make a password ')
strong_symbol = '!!'
mediocure_symbol = '@'
# username creater
if username.upper:
      print('good username')
else:
      print('please add a capital letter')

# password creater
if '!!' in password:
    print('strong password')
elif '@' in password:
        print('mediocure password')
else:
       print('weak password, please add either the @ or !!')```

if username.upper:

This is broken, btw. upper is a function, so it needs to be called. You're checking if the function itself is true, which it always will be.

Also, that will uppercase the string, not check if it's upper.

You want isupper()

oh huh didnt show a error it works

ill change it

[old ginkgo]

That's why it's important to test your code. The code is valid, it just doesn't do what you intended.

If you're going to have a check that checks if the username is uppercase, as part of your testing, you should have given it a string that you expected would cause "please add a capital letter" to print out.

You would have found that it's impossible for that to be printed.

[obsidian prawn]

well im testing it and it works \

i know its wrong but it worls

its seeing that i added a uppercase and its printing it out

[old ginkgo]

It doesn't work if it doesn't do what you expected. Again, "please add a capital letter" would never print in your original code, and it's unlikely that that was intentional.

As part of testing, you need to make sure all the code works and not just a single execution path. That's important, because if the input ever changes to something other than what you tested, you have no idea what your program will do.

oh i see my bad

so i know i need a database but i never did that before

what i understand is that you cant import like a regular module

right?

[old ginkgo]

You don't technically need a full database, but that is the best solution to storing data. Have you ever used open before to read/write files?

[obsidian prawn]

yes

oh i see so i would either make a text file then do file.open and do write or read

[old ginkgo]

I would personally make sure you're capable of using a text file to store login information first, then change to using a database. The database is the better solution, but knowing how to read and write text files to do actual tasks is important to understand as well.

But ya, use open to write information when they create an account, and read the file to see login information when they want to log in.

[obsidian prawn]

well i have used txt files in my code before but never made a database before

[old ginkgo]

If you're confident that it's not worth trying to use a text file here, then you can go straight to using a database. For this, just use sqlite, which comes with the Python standard library.

[obsidian prawn]

so i would import it?

[old ginkgo]

SQLite is far easier to manage than enterprise-ready databases managers which require servers.

[old ginkgo]

You import the library, yes. Then use the library to create a database file. Give this whole section/page a read over: https://docs.python.org/3/library/sqlite3.html#tutorial

Ok, maybe not the whole page. Definitely the tutorial section, though.

[obsidian prawn]

ok so i would import it then make a cursor then make a table then add the username and password into it?

or do i have it backwards would i make the table first or the cursor

[old ginkgo]

You need the cursor to be able to do inserts and to create the table.
